北斗地基增强系统(郑州)区域网性能测试与分析

Performance Test and Analysis of the Beidou Foundation Reinforcement System(Zhengzhou) Regional Network

本文介绍我国北斗卫星导航系统发展现状以及北斗地基增强系统(郑州)区域网的基本情况。通过野外测试,得到各性能指标的测试数据,并对测试数据中异常现象进行分析,查找数据表象下的实质原因。通过性能测试综合分析得出,北斗地基增强系统(郑州)区域网的建设满足实施方案指标,可实现实时厘米级定位服务,为全国类似北斗地基增强系统的建设奠定基础。

This paper introduced the development status of the Beidou satellite navigation system in China and the basic situation of the Beidou foundation reinforcement system （Zhengzhou） regional network.Through field test, the test data of various performance indexes were obtained, and the abnormal phenomena in the test data was analyzed, and the substantial reasons were found under the data representation.Through the comprehensive analysis of performance test, it was concluded that the construction of the Beidou foundation reinforcement system （Zhengzhou） regional network met the implementation plan index, and could achieve real- time centimeter level positioning service, laying the foundation for the construction of similar Beidou foundation reinforcement system in China.
